Fix the error `Failed to Write Core Dump’ in Minecraft

Fix the error `Failed to Write Core Dump' in Minecraft

Update the latest Intel graphics card driver (if available).

If you are using an Intel integrated graphics card, you will most likely have an issue with the ig9icd64.dll file. This file is part of the OpenGL driver for the Intel graphics gas pedal.

If this scenario applies to your current situation, you can solve the problem by updating all graphics drivers with the Intel Update Assistant.

Many affected users who previously could not join and create Minecraft servers have confirmed that this has finally made the game stable.

Here is a quick guide on how to update your Intel graphics drivers to the latest version:

  1. Go to their website and click the “Get Started” button.
  2. Then wait for the initial scan to complete. Once the process is complete, click the “Download All” button and wait for the download to complete.
  3. Once the download is complete, double-click on each installation file and follow the instructions on the screen to complete the driver installation.
  4. After successfully installing each new update, restart your computer and see if the `Failed to Write Core Dump’ message resolves when you try to connect or create a Minecraft server.
Force Vsync and Triple Buffering in Minecraft (Nvidia only)

If you are using a mid-to-high-end Nvidia GPU, you will most likely encounter the “Failed to Write Core Dump” error because your current video card settings do not force you to use VSync when playing Minecraft.

This setting can also be forced in the game settings, but the ideal way is to go through the Nvidia Control Panel. To solve this problem, you need to go to the Java path and add Javaw.exe to the list of controls.

You can then force both settings to be used by any program that uses Javaw.exe (including Minecraft). Here is a quick step-by-step guide on how to enable VSync and triple-buffering in the Nvidia Control Panel’s 3D Settings menu:

  1. Right-click an empty space on your desktop and select Nvidia Control Panel from the new pop-up menu that appears.
  2. While in the Nvidia Control Panel, select Manage 3D Settings on the left menu (under 3D Settings).
  3. Then switch to the right-hand menu and select the Program Settings menu. From there click Add -> Browse and navigate to the Java installation location, select the javaw.exe file and click Open.
  4. Once the executable has loaded, scroll down through the program settings and look for Vertical Sync and Triple Buffering. Once you see them, use the appropriate drop-down menu to change the default settings for both to ON.
  5. After applying both settings, click Apply to make the changes permanent.
  6. Try joining or creating a Minecraft server again and see if the problem is resolved.
Reinstall the AMD Catalyst utility (AMD only)


If you are using an AMD GPU, you may encounter the message “Failed to write core dump”. Minimum dumps are not enabled by default on client versions of Windows due to a partially corrupted AMD software installation.

In this case, you can solve the problem by uninstalling the current AMD software or AMD directory installation and reinstalling the latest version through official channels.

Here’s a quick step-by-step guide on how to do this:

  1. Press the Windows + R key to open the “Run” dialog box. Then type “appwiz.CPL” and press Enter to open the “Programs and Features” menu.
  2. While in the “Programs and Features” screen, scroll through the list of installed applications and find the AMD installation you want to remove. When you find your AMD installation, right-click on it and select Uninstall from the pop-up menu.
  3. At the confirmation prompt, click Ok and follow the on-screen instructions to complete the uninstall process.
  4. Restart your computer and wait for the next boot process.
  5. Visit the manufacturer’s website and download the latest version of AMD Catalyst. Once the download is complete, open the executable installation file and follow the on-screen instructions to complete the installation.
  6. After installing the new version, restart your system, and the next time you start up, make sure the problem is resolved by trying to connect or create a Minecraft server.
Try creating the dump file manually

Sometimes you can try to get Windows to create a dump file using Task Manager, which can solve the problem. To create a dump file, follow these steps.

  1. Open Minecraft or the Minecraft launcher.
  2. Right-click on the taskbar, then click “Task Manager” (you can also hold down Ctrl+Shift+Esc).
  3. Once the task manager is open, right-click on “Java(TM) Platform SE Binary” (if you can’t find it, right-click on “Minecraft Launcher”).
  4. Now click on the “Create dump file” option.
  5. Wait for Windows to create a dump file for the selected process.

Now restart your computer and try playing Minecraft again.
